[Clinical research advances of endoscopic tympanoplasty].

Endoscopic ear surgery has been applied in therapy of chronic suppurative otitis media and middle ear cholesteatoma these years. Offering a minimally invasive approach, it requires more experience and skills. The comparative outcomes of endoscopic and microscopic tympanoplasty remains unclear. Therefore, this article summarizes clinical research results of two surgical approaches, hoping to provide references for choice of endoscopy on treatment of chronic suppurative otitis media and middle ear cholesteatoma.
